Not quite. We can do little that will result in overnight changes, but there are small, almost imperceptable steps that can and should indeed be made. And there are larger ones that offer greater results over the long term.
We'll need both approaches, and they'll have to be applied as and as determined by those taking thoise steps- not everyone has the same talents or opportunities that others may have, but everyone can do something.
Not my words if I recall. Perhaps a different post.
